| 摘 要： | 通过对中外跳远运动员的对比分析发现,中国运动员只有在加大水平速度的同时,进一步减少其速度的损失率才能更有效地提高跳远成绩。同时,找出了造成水平速度损失的原因、水平速度损失率对跳远成绩的影响以及减少水平速度损失的对策。得出结论,跳远中必须在高速助跑与快速起跳结合的同时,控制好最后2 步步长的合理变化。

| Abstract: | By comparing our long jumpers with foreign athletes, the author thinks that the only way to improve the performance of long jump is to increase the horizontal velocity and decrease the loss ratio of velocity. Moreover, the author found out the reason of leading to the loss of horizontal velocity and the way to decrease it. The result shows that the reasonable change of length for last two steps must be controlled in the long jump. |
